Basic material composition of PET packaging box:
PET is a milky white or light yellow highly crystalline polymer with a smooth, shiny surface. Good dimensional stability, small wear and high hardness, with the greatest toughness of thermoplastics: good electrical insulation performance, little affected by temperature. Non-toxic, weather resistant, low water absorption.
Advantages of PET packaging box:
1. Has good mechanical properties, impact strength is 3~5 times of other films, good folding resistance;
2. With excellent high and low temperature resistance, it can be used in the temperature range of 120℃ for a long time.
Short-term use can withstand 150℃ high temperature, can withstand -70℃ low temperature, and high and low temperature has little effect on its mechanical properties;
4. Low permeability of gas and water vapor, and excellent resistance to gas, water, oil and odor;
5. High transparency, can block ultraviolet light, good gloss;
6. Non-toxic, tasteless, good health and safety, can be directly used for food packaging.
PET is widely used in fiber, film and engineering plastics. PET fibers are mainly used in the textile industry. PET film is mainly used in electrical insulation materials, such as capacitors, cable insulation, printed circuit wiring substrate, electrode groove insulation and so on. Another application area of PET film is wafer base and band, such as motion picture film, X-ray film, audio tape, electronic computer tape, etc. PET film is also used to vacuum transfer aluminum into metallized film, such as gold and silver wire, micro capacitor film, etc. Film sheet can be used for all kinds of food, medicine, non-toxic aseptic packaging materials. Glass fiber reinforced PET is suitable for electronic and electrical and automotive industries, used in various coil skeleton, transformer, TV, recorder parts and shell, automobile lamp holder, lampshade, white heat lamp holder, relays, sunlight rectifier, etc.
PET boxes are a very premium option. In daily life, there is a great demand for the use of PET packaging boxes. Many manufacturers and consumers will use PET packaging boxes in the processing and production, and the demand for PET packaging boxes in daily life is very high. The above simple expression PET packaging box structure and application.
